Hierarchy generation for numerical data

Web[1] A two-dimensional numerical model is used to study the diapycnal flow through a tidal front with passive tracers. In a basic numerical experiment a passive tracer is released into the bottom water at the offshore edge of a tidal front, and it subsequently moves on-bank with a velocity that decreases with time. This qualitatively agrees with a recent field … Web11 de fev. de 2024 · Algorithm flow chart of multi-scale numerical model algorithm for lubricated MTS with TME considering ATSLB capacity is indicated in Figure 5.

WebAn information-based measure called \entropy" can be used to recursively partition the values of a numeric attribute A, resulting in a hierarchical discretization. Such a discretization forms a numerical concept hierarchy for the attribute. Given a set of data tuples, S, the basic method for entropy-based discretization of A is as follows.

Web28 de mar. de 2010 · Algorithm to generate numerical concept hierarchy. I have a couple of numerical datasets that I need to create a concept hierarchy for. For now, I have been doing this manually by observing the data (and a corresponding linechart). Based on my intuition, I created some acceptable hierarchies. WebA concept hierarchy is a kind of concise and general form of concept description that organizes relationships of data and expresses knowledge as a tree-like or partial ordering structure. In this paper, we propose an approach to generate concept hierarchies automatically for a given data set with nominal attributes based on rough entropy.

WebData hierarchy refers to the systematic organization of data, often in a hierarchical form. Data organization involves characters, fields, records, files and so on. [1] [2] This … WebTraditionally, these hierarchies were created by the data owner with help from the domain experts. But while it is feasible to construct a hierarchy of small size, the effort increases for hierarchies that have many levels. Therefore, new approaches of creating these numerical hierarchies involve their automatic/on-the-fly generation.
